On June 16, 2025, Austrian firm Schiebel introduced a reinforced configuration of its S-300 rotary-wing unmanned aerial vehicle (UAV) during its public presentation at Paris. Now equipped with the L3HARRIS WESCAM MX-10 turret, IMSAR NSP-3 radar, a secondary optical system in the nose, and an anti-submarine warfare (ASW) sonobuoy pod, the platform marks a notable entry into multidomain maritime surveillance and naval support. The expanded payload transforms the S-300 from a conventional ISR asset into a full-fledged system capable of naval reconnaissance and undersea warfare.

The Schiebel S-300 is a rotary-wing UAV classified under the tactical maritime surveillance and anti-submarine warfare category. With a maximum takeoff weight of around 250 kg and derived from the Camcopter S-100 architecture, it retains VTOL capability while supporting modular payload configurations. The addition of L3HARRIS WESCAM MX-10 for electro-optical and infrared imaging and the NSP-3 radar pod from IMSAR significantly extends its ISR and targeting capabilities. Notably, a new under-nose sensor suggests enhanced navigation or auxiliary reconnaissance functions, while the mounted ASW pod demonstrates the UAV’s readiness for sonobuoy deployment and submarine detection tasks.
Developed by Vienna-based Schiebel Group, the S-300 traces its lineage to the proven S-100 system, long in service with multiple navies. The S-300 was gradually designed to address heavier payload needs, longer endurance, and greater multi-mission flexibility. Paris Air Show 2025 marked the first public appearance of the S-300 with its full naval configuration. The integration of cutting-edge American and European sensors points to Schiebel’s ambition to position the S-300 within NATO-compatible frameworks, meeting the rising demand for compact, sea-based ASW solutions without relying on manned helicopters.
Compared to smaller UAVs like the Skeldar V-200 or heavier rotorcraft like the MQ-8C Fire Scout, the S-300 offers a unique compromise between payload and deployment flexibility. Its ability to operate from smaller naval platforms without a runway and its compatibility with NATO-standard sensors give it an edge in littoral operations and anti-submarine patrols. Unlike fixed-wing UAVs, it can hover for vertical ISR collection or sonobuoy deployment. The ASW integration is a rare feature in this weight class and could signal a cost-efficient alternative to conventional manned ASW patrols, particularly for smaller navies.
Its deployment potential is underscored by the rising geopolitical tension in maritime chokepoints and buffer zones. The Baltic Sea and North Sea have seen increased naval activity amid Russian military posturing, while the Red Sea has emerged as a hotspot due to Houthi attacks and Iranian influence. A compact ASW UAV like the S-300 could provide vital coverage for NATO ships operating without organic helicopter detachments. With modular payloads, it can adapt to signals intelligence, maritime patrol, and even underwater threat detection. Its relevance is amplified by the growing demand for unmanned force multipliers in A2/AD environments.
The unveiling of the S-300 in its ASW configuration marks a turning point for medium-weight rotary UAVs, pushing them into mission profiles once reserved for manned platforms. By integrating advanced sensors and ASW capability into a compact unmanned system, Schiebel offers navies a scalable solution to face the rising threat of submarine activity in contested waters. As NATO fleets stretch their presence across multiple maritime fronts, platforms like the S-300 could become central to maintaining underwater situational awareness with reduced risk and cost.
